Abstract

In this paper, the pupil energy distribution is calculated with parameters of digital versatile disk and by using the scalar diffraction theory. In view of radial tilt, a radial tilt angle in pit model is added, and consequently, a simulation of push-pull tracking error is given when a radial tilt error occurs. Furthermore, the influence of radial tilt is analyzed by using push-pull tracking servo method.
